Abstract: A cart comprises a body structure and at least one wheel connecting structure. The body structure comprises a support shaft, a first frame member and a second frame member. Both the first and second frame members are disposed on the support shaft. The wheel connecting structure is disposed on one end of the support shaft and comprises a driving assembly, a rotating assembly, a linking assembly, and an energy assembly. The driving assembly is connected to the first frame member. One end of the rotating assembly is disposed in correspondence with the one end of the support shaft, and the other end of the rotating assembly is mounted on a wheel member. The linking assembly is disposed between the driving assembly and the rotating assembly. The linking assembly comprises a pushing unit, which is pivotally connected to the rotating assembly. The energy assembly is connected to the linking assembly.

Abstract: Disclosed is a cart of a telescopic structure, comprising: a telescopic rod; a telescopic tube, where at least one of the telescopic tube and the telescopic rod have a hollow structure acting as an accommodation space that is required when the telescopic tube and the telescopic rod collapse into each other; a linkage mechanism connected to one end of the telescopic tube that is away from the hollow structure, and connected to one end of the telescopic rod that is close to the hollow structure; and a frame connected to the linkage mechanism. When the frame is rotated with respect to the linkage mechanism and collapses, the telescopic tube is also rotated with respect to the linkage mechanism, and one of the telescopic tube and the telescopic rod is retracted into the other thereof by means of the linkage mechanism.

Abstract: A handbrake structure includes a fixing base, a linking member and a brake handle. The fixing base is located on a handle of a moving apparatus. The linking member is located on the fixing base, wherein a first portion of the linking member is connected to a first brake wire, and a second portion of the linking member has a first limit part. The brake handle is located on the linking member, wherein a first portion of the brake handle is connected to a second brake wire. When the brake handle is rotated in a first direction, the brake handle pushes the first limit part to rotate the linking member, and the linking member pulls the first brake wire. When the brake handle is rotated in a second direction different from the first direction, the brake handle pulls the second brake wire.

Abstract: Provided herein is a baby stroller, which has an expanded mode and a folded mode, and includes a lower arm set, a connection part, a front wheel frame, a slide block, a rear wheel set, an upper frame, a first link rod set, a handling tube, a supporting rod set, two seat supports, and two second link rods. Due to the couplings between the slide block, the handling tube and the upper frame and the coupling between the slide block and the rear wheel rocker arms, the baby stroller may easily be folded so that it occupies considerably less space, and thereby improve its portability and facilitate its stowage and transportation.

Abstract: Provided herein is a baby stroller, which has expanded mode or folded mode, including a lower frame, a slide block, a pull rod set, a rear wheel link rod, a rear wheel frame, an upper arm set, a link rod set, a connection rod set, the first handle rod set, the second handle rod set, and a front wheel frame. Through the slide block and the interaction between each component to concurrently actuate the upper arm set, the first handle rod set, and the second handle rod set, the baby stroller can be easily folded to minimize it occupying space for easier stowing and transporting.
